IPC: H01L21/027
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To enable the parallel movement of a leveling table in vertical axis direction with keeping it tilted at a const. angle, without needing a complicated arithmetic process. SOLUTION: A leveling table control circuit 54 in a control system 33 feeds the same drive voltage to d-c motors 40, 42, 44 for driving drive shafts for a specified time. Pulse encoders 46, 48, 50 generate pulses.
